Winchester SX4 Left-Hand Autoloader

The SX4 represents Winchester's evolution of the legendary Super X3 platform, engineered specifically for hunters who demand reliability and intuitive handling in the field.

Key Features

  • Left-hand configuration for southpaw shooters
  • 3-inch chamber accommodates standard and magnum loads
  • 28-inch ventilated rib barrel for improved sight picture and reduced heat distortion
  • Matte black finish minimizes glare and reflection to avoid spooking game
  • 4+1 capacity (four in magazine, one in chamber)
  • Three interchangeable choke tubes for pattern versatility

Design and Function

Winchester engineered the SX4 with larger, more accessible controls—a practical advantage when hunting in wet weather or cold conditions where gloved hands are the norm. The shotgun's all-black exterior presents a non-reflective profile ideal for serious hunting applications.

The inertia-driven action cycles reliably across a wide range of ammunition, from light target loads to heavy magnum rounds. This versatility makes the SX4 equally at home in the duck blind, the upland field, or at the clay range.
